Regina is back!

Filed under: 3-manifolds,Computation and experiment,Triangulations — Benjamin Burton @ 5:32 pm

For those interested in computation with triangulations and normal surfaces:

It’s been a while coming, but Regina 4.90 finally went live last week!  This is the release that was previewed at the HyamFest.  There have been many changes since the last release 2+ years ago: see what’s new in this version, or check out the user handbook to learn more about what Regina can do.

If you use GNU/Linux, Regina is easy to install (just download a package).  If you use MacOS, it’s still complex (you need fink) but the end result is much cleaner than ever before (it feels and behaves like a native Mac app).

See some screenshots after the jump, or head across to regina.sourceforge.net to learn more.
